Abstract (en)
[origin: WO2012172422A1] A cooling apparatus for an internal combustion engine includes a fan that cools a coolant by operating at least at a first drive voltage and a second drive voltage higher than the first drive voltage; and a control unit that drives the fan at the first drive voltage when a vehicle is driven at a low vehicle speed that is a vehicle speed lower than a vehicle speed threshold and a coolant temperature is higher than a fan low-voltage activation threshold.
